After the Federal Reserve's decision to cut rates, the dollar strengthened to levels not seen in more than two years. There are fears that rates will remain at 4% until at least the middle of next year, which will affect the markets and slow down the economy. This strengthening of the dollar is putting pressure on other currencies, including the euro, which could lead to further weakening of the euro against the dollar, given forecasts of higher rates in the US in the coming years.
